Description

Scharniere mit aussenliegendem, beweglichem Rotationszentrum werden vielfach für die Türen von Möbeln und Haushaltgeräten gebraucht, da sie platzsparend und versteckt angeordnet werden können, und weil sie gleichzeitig ermöglichen, bei geschlossener Tür auch dann eine glatte Aussenfläche zu erhalten, wenn die Tür mit einer verhältnismässig dicken, sogenannten Dekorplatte verkleidet ist. Insbesondere bei den verhältnismässig schweren, um eine horizontale Achse schwenkenden Türen von Waschmaschinen, insbesondere Geschirrspülmaschinen, sind noch weitere Bedingungen zu erfüllen: ihr Gewicht muss weitgehend durch ein Gegengewicht oder eine Feder kompensiert werden, das Scharnier muss sehr robust sein und dennoch eine geringe Breite aufweisen, um Platz für den Bottich der Maschine sowie die nötigen Dichtungen zu lassen, der Anschlag bei voll geöffneter, in der Regel etwa horizontaler Endlage der Tür sollte stark genug sein um fallweise das Gewicht eines kletternden Kleinkindes aufzunehmen, und die Öffnungskurve des Scharniers muss ein gutes Schliessen der Dichtungen sowie einen freien Weg der Dekorplatte auch bei Schrank-Hocheinbauten gewährleisten.Hinges with external, movable Rotation centers are often used for the doors of furniture and household appliances because they save space and can be hidden and because they are concurrent allow one with the door closed to get a smooth outer surface if the door with a relatively thick, so-called decorative panel clad is. Especially with the relatively heavy, doors of washing machines pivoting about a horizontal axis, especially dishwashers are still to meet other conditions: their weight must be largely compensated by a counterweight or a spring the hinge must be very robust and yet have a small width to accommodate the tub the machine and the necessary seals, the Stop with fully open, usually approximately horizontal End position of the door should be strong enough to be used occasionally to bear the weight of a climbing toddler, and the opening curve of the hinge must be a good one Close the seals and a free path for the decorative panel also guarantee for built-in cupboards.

Die Patentschriften CH 682 168 A5 und EU 0 437 815 B1 zeigen ein für diesen Zweck geschaffenes sogenanntes Vierpunktscharnier, welches aber relativ breit baut, baulich aufwendig ist und eine getrennte, angelenkte Sperrklinke als Anschlag benötigt, welche im verfügbaren Bauraum nur eine begrenzte Lastgrenze aufweist. Zudem ist die Öffnungskurve dieser Lösung nicht ganz befriedigend. Es sind weitere Scharniere der hier betrachteten Art bekannt, und etwa in den US-A-2 648 093, welche die Merkmale des Oberbegriffs des Anspruchs 1 offenbart, und US-A-3 131 423 beschrieben. Diese weisen jedoch keine im Verhältnis zu ihren Dimensionen speziell hoch belastbare Anschläge auf und benötigen solche auch nicht, weil sie für Türen vorgesehen sind, die in ihrer offenen Endstellung angenähert vertikal, und nicht horizontal stehen. Eine in Dokument EP 0 744 521 A1 vorgeschlagenes Scharnier besitzt zwar einen gesonderten Anschlag, der aber mangels symmetrischer Anordnung in bezug auf die tragenden Scharnierteile nicht optimal wirkt. Andere bekannte Ausführungen besitzen keinen gesonderten Anschlag, sei es weil sie hinreichend federbelastet sind, um ohne einen solchen auszukommen, wie etwa in der deutschen Auslegeschrift 1 191 257 dargestellt, sei es weil sie für Aufgaben geschaffen wurden, bei denen sich ein gesonderter Endanschlag erübrigt, wie etwa im US Patent 4 095 311 beschrieben. Hier soll die Erfindung Abhilfe schaffen.The patents CH 682 168 A5 and EU 0 437 815 B1 show one created for this purpose so-called four-point hinge, but which is relative broadly built, structurally complex and a separate, articulated Pawl needed as a stop, which in available space has only a limited load limit. In addition, the opening curve of this solution is not quite satisfactory. There are other hinges here considered type, and approximately in US-A-2 648,093, which discloses the features of the preamble of claim 1 and US-A-3 131 423. However, these point none especially high in relation to their dimensions resilient stops and do not need such, because they're intended for doors that are in their open End position approximately vertical, and not horizontal stand. One proposed in document EP 0 744 521 A1 Hinge has a separate stop, the but due to the lack of a symmetrical arrangement with respect to the load-bearing hinge parts does not work optimally. Other known ones Designs do not have a separate stop, be it because they are sufficiently spring loaded to be without to get along, such as in the German interpretation 1 191 257, either because they are for Tasks were created in which a separate There is no need for an end stop, such as in US Pat. No. 4,095,311 described. The invention is intended to remedy this.

Zu diesem Zweck ist die Erfindung wie im Hauptanspruch beschrieben definiert. Die Verteilung der Verbindungsorgane beidseits der Platten sichert eine weitgehend symmetrische Kräfteverteilung und gestattet es, äusserst wirksame Endanschläge einzurichten, die bei voll geöffneter Tür auf entgegengesetzten Seiten des momentanen Rotationszentrum zu liegen kommen, wodurch die Scharnierachsen auch bei grosser Belastung geschont werden. In einer bevorzugten Ausführung der Erfindung sind die Anschläge in der offenen Endstellung der Tür gegen ein seitliches Ausweichen geführt, was die Robustheit noch erhöht.For this purpose, the invention is as in Main claim described defined. The distribution of the Connecting elements on both sides of the plates secure one largely symmetrical distribution of forces and allowed it to set up extremely effective end stops, which at fully open door on opposite sides of the current one Center of rotation come to rest, whereby the Hinge axes can be protected even under heavy loads. In a preferred embodiment of the invention the stops in the open end position of the door a lateral evasion resulted in the robustness still increased.

Im folgenden soll die Erfindung anhand der Beschreibung eines Ausführungsbeispiels und der Zeichnung näher erläutert werden.In the following the invention with reference to the Description of an embodiment and the drawing are explained in more detail.

Es zeigen :

  • Figur 1 eine schematische Seitenansicht einer Ausführungsform der Erfindung bei geschlossener Tür;
  • Figur 2 eine teilweise Aufsicht der Ausführungsform der Figur 1;
  • Figur 3 eine schematische Seitenansicht der Ausführungsform der Figur 1 bei voll geöffneter Tür;
  • Figur 4 einen Längsschnitt durch den Kipphebel der Figuren 1 und 3.
    • Show it :
  • Figure 1 is a schematic side view of an embodiment of the invention with the door closed;
  • Figure 2 is a partial plan view of the embodiment of Figure 1;
  • Figure 3 is a schematic side view of the embodiment of Figure 1 with the door fully open;
  • 4 shows a longitudinal section through the rocker arm of FIGS. 1 and 3.

    • In Figur 1 bezeichnet 1 die Trägerplatte eines auf dem Sockel 5 eines Gerätes, beispielsweise eines Geschirrspülers, befestigten Scharniers, dessen schwenkbare Platte 2 die Türverkleidung 6 des Gerätes trägt. Die Platten 1, 2 sind durch einen ersten 3 und einen zweiten 4 Gelenkhebel verbunden, welche in ersten Drehpunkten 7, 8 an der Trägerplatte 1 und in zweiten Drehpunkten 9, 10 an der schwenkbaren Platte 2 angelenkt sind, so dass sich das momentane Rotationszentrum des Scharniers im Schnittpunkt Z der durch die beiden Drehpunkte 7, 9 und 8, 10 je eines Gelenkhebels bestimmten Geraden befindet. Die strichpunktierte Linie L zeigt die Bahn der unteren Kante der Türverkleidung 6 beim Öffnen, d.h. Herabschwenken der Tür.In Figure 1, 1 denotes the carrier plate one on the base 5 of a device, for example one Dishwasher, attached hinge, its pivoting Plate 2 carries the door panel 6 of the device. The Plates 1, 2 are by a first 3 and a second 4 articulated lever connected, which in first pivot points 7, 8 on the carrier plate 1 and in second pivot points 9, 10 are articulated on the pivotable plate 2, so that the current center of rotation of the hinge at the intersection Z each through the two pivot points 7, 9 and 8, 10 a straight line. The dash-dotted line L shows the path of the lower edge the door trim 6 when opening, i.e. Swinging down the Door.

    Wie aus der Figur 2 ersichtlich, fluchten die Trägerplatte 1 und die schwenkbare Platte 2 im Bereich der Gelenkhebel 3 und 4, von denen jeder mit einem gleichgeformten, symmetrisch auf der anderen Seite der Platten angeordneten Gegenstück 3a, 4a gepaart ist und mit diesem zusammen ein Verbindungsorgan bildet, welches die Kräfte symmetrisch zwischen den Platten überträgt. Dadurch treten an diesen Teilen praktisch nur zu den Plattenebenen parallele Kräfte auf, und sie können entsprechend leicht und platzsparend ausgeführt werden. Insbesondere kann die in Figur 2 mit B bezeichnete Baubreite dieses Scharnierteils auf ein Minimum reduziert werden, was insofern wichtig ist, als es genügend Platz für den bei einem Geschirrspüler nahe an das Scharnier angrenzenden Bottich schafft.As can be seen from Figure 2, the Carrier plate 1 and the pivotable plate 2 in the area the articulated levers 3 and 4, each with a uniform, symmetrical on the other side of the Plates arranged counterpart 3a, 4a is paired and together with this forms a connecting organ, which transmits the forces symmetrically between the plates. As a result, practically only occur on these parts Plate planes have parallel forces, and they can act accordingly can be carried out easily and in a space-saving manner. In particular can the overall width designated with B in Figure 2 this hinge part can be reduced to a minimum, which is important in that there is enough space for the in a dishwasher close to the hinge Vat creates.

    Figur 3 zeigt eine der Figur 1 entsprechende Seitenansicht desselben Ausführungsbeispiels bei bis zum Anschlag geöffneter, d.h. horizontal heruntergeklappter Tür. Da beim Öffnen der Tür der zweite Drehpunkt 9 um nahezu 90° um den ersten Drehpunkt 7 herumschwenkt, weist die Trägerplatte 1 im Bereich zwischen den beiden ersten Drehpunkten 7 und 8 eine mit A bezeichnete Ausnehmung auf, in welche die den Drehpunkt 9 tragende Nase der schwenkbaren Platte 2 einfahren kann, wie aus Figur 3 ersichtlich. Dabei durchdringt die im Drehpunkt 9 befindliche, die Gelenkhebel 3 und 3a verbindende Achse die Mittelebene der Trägerplatte 1.Figure 3 shows one corresponding to Figure 1 Side view of the same embodiment at up to Stop open, i.e. horizontally folded down Door. Since when the door is opened the second pivot point 9 is almost Pivots 90 ° around the first pivot point 7 the carrier plate 1 in the area between the first two Pivots 7 and 8 have a recess labeled A. in which the nose carrying the pivot point 9 can pivot retractable plate 2, as shown in Figure 3. This penetrates the the articulated lever 3 and 3a connecting axis the median plane the carrier plate 1.

    Um das Gewicht der Tür im teilweise offenen Zustand zu kompensieren, ist am Ende E eines von der Tür wegragenden Flügels 2a der schwenkbaren Platte 2 eine Zugstange 11 angelenkt, deren anderes Ende in F an einem im Punkt K der Trägerplatte 1 gelagerten Kipphebel 14 angelenkt ist. Das andere Ende dieses Kipphebels wirkt über eine Stellschraube 15 auf ein eine Druckfeder 16 aufweisendes, einstellbares Federbein 17, das sich an der mit M bezeichneten Stelle gegen die Trägerplatte 1 abstützt, um dem Gewicht der teilweise geöffneten Tür entgegenzuwirken. Die Geometrie des aus Federbein, Kipphebel, Zugstange und Flügel bestehenden Rückholmechanismus kann leicht so gewählt werden, dass ein gleichmässiger, integrierter Gewichtsausgleich über den ganzen Öffnungswinkel von 90° der Tür erzielt wird. Da das Federbein 17 samt der Druckfeder 16 einen relativ grossen Durchmesser aufweist, und daher verlangt, dass der axial daran angelenkte Kipphebel 14 einen entsprechenden Abstand von der Trägerplatte 1 aufweist, ist diese (wie aus Fig. 2 besser ersichtlich) an den Stellen R und S so gekröpft, dass der Flügel 2a der schwenkbaren Platte 2, die Zugstange 11, der Kipphebel 14 und die Mittelebene des Federbeins 17 hinreichend fluchten, um im wesentlichen nur parallel zur Trägerplatte 1 wirkende Rückstellkräfte zu erzeugen. Fallweise kann der Kipphebel 14 doppelwandig ausgeführt und wie in Fig. 4 gezeigt gekröpft sein, um die anderen Teile von nicht zu den Drehachsen senkrechten Kräften zu entlasten, so dass diese Teile besonders leicht ausgeführt werden können.To the weight of the door in the partially open To compensate for the condition, at the end E is one of the doors projecting wing 2a of the pivotable plate 2 a Drawbar 11 articulated, the other end in F on one at the point K of the support plate 1 mounted rocker arm 14 articulated is. The other end of this rocker arm works over a set screw 15 on a compression spring 16, adjustable shock absorber 17, which is on the M designated point against the support plate 1 to counteract the weight of the partially opened door. The geometry of the strut, rocker arm, tie rod and wing existing return mechanism can easily be chosen so that a uniform, integrated Weight compensation over the entire opening angle of 90 ° the door is scored. Since the strut 17 together with the compression spring 16 has a relatively large diameter, and therefore requires the rocker arm axially hinged to it 14 a corresponding distance from the carrier plate 1 this is (as can be seen more clearly from FIG. 2) cranked at points R and S so that wing 2a the pivotable plate 2, the pull rod 11, the rocker arm 14 and the median plane of the strut 17 is sufficient align to essentially only parallel to the support plate 1 effective restoring forces. Occasionally can the rocker arm 14 is double-walled and as in Fig. 4 be cranked to the other parts of not to relieve forces perpendicular to the axes of rotation, so that these parts can be carried out particularly easily.

    Um die Bewegung der Tür zu begrenzen, stossen bei voll geöffneter Tür die im Bereich der Gelenkhebel 3, 4 und 3a, 4a (von denen die letzteren zwei nur in Fig. 2 sichtbar sind) fluchtenden Platten 1, 2 an der in Fig. 3 mit P bezeichneten Stelle aufeinander. Damit die Trägerplatte 1 und die schwenkbare Platte 2 beim Anschlag nicht nebeneinander geraten und aneinander vorbeigleiten sind die Gelenkhebel 3, 3a dreieckig ausgebildet und von genügender Fläche, um die Platten zwischen sich zu führen. Dies sichert auch dann einen sauberen Anschlag, wenn die Platten dünn sind. Ein weiterer Anschlag Q besteht zwischen dem Ende E des Flügels 2a und einer an der Trägerplatte 1 vorgesehenen Nase N, welche beispielsweise direkt oder indirekt gegen die in E befindliche Achse oder gegen die Zugstange 11 stossen kann. Wie aus Fig. 3 ersichtlich, liegt das momentane Rotationszentrum Z bei voll geöffneter Tür fast genau in der Mitte zwischen den beiden Endanschlägen P und Q. Die Symmetrie dieser Anordnung sowie ihre verhältnismässig langen Hebelarme erlaubt eine grosse Belastung der offenen Tür - etwa durch ein herumturnendes Kleinkind - ohne die Gelenke 7 - 10 merklich zu beanspruchen. Infolge der geometrischen Symmetrie bleiben dabei die Gelenke des Vierpunkte-Scharniers auch dann entlastet, wenn die beiden Anschläge relativ grosse Toleranzen aufweisen.To limit the movement of the door, push with the door fully open, in the area of the articulated lever 3, 4 and 3a, 4a (the latter two only in Fig. 2 are visible) aligned plates 1, 2 on the in Fig. 3rd point designated P on each other. So that the carrier plate 1 and the pivoting plate 2 not at the stop come together and slide past each other the articulated levers 3, 3a triangular and of sufficient Area to guide the plates between them. This ensures a clean stop even when the Plates are thin. Another stop Q exists between the end E of the wing 2a and one on the support plate 1 provided nose N, which for example directly or indirectly against the axis in E or can hit against the tie rod 11. 3, the current rotation center Z is enclosed fully open door almost exactly in the middle between the two end stops P and Q. The symmetry of this arrangement as well as their relatively long lever arms a large burden on the open door - for example by a toddler gymnastics - noticeable without the joints 7 - 10 to claim. Due to the geometric symmetry the joints of the four-point hinge remain then relieved when the two stops are relatively large Show tolerances.

    Schliesslich sei bemerkt, dass eine Ausführung des Scharniers es gestattet, die Geometrie der vier Drehpunkte so zu wählen, dass die Öffnungskurve in den ersten 5° des Öffnungswinkels einem besonders steilen Anhub des Türblattes entspricht, was für Schrank-Hochbaueinheiten besonders erwünscht ist da es die problemlose Verwendung eines einteiligen Türblattes ermöglicht.Finally, it should be noted that an execution of the hinge allows the Select geometry of the four pivot points so that the opening curve especially in the first 5 ° of the opening angle steep rise of the door leaf corresponds to what Cabinet building units are particularly desirable since it the trouble-free use of a one-piece door leaf allows.
